I don't think that had anything to do with nationality; an admiral, who happened to be Russian (or, at least, have a Russian name; he spoke with a Canadian accent, but, then, Translator Microbes conveniently convert all languages, human or alien, to English spoken in a Canadian accent - must've gotten them from the same store as Stargate), was tagged to get the SSV Normandy in his Flotilla; it was reassigned to Shepard, put under alien oversight (the Citadel Council) and put aliens on the crew. That's what he was pissed about.
But there are indications about things changing - a lot of corporations, ship classes and names, etc. tend to be Russian or Russian-derived, but spacers tend to be American or Canadian in their cultural outlook, while Los Angeles, Mexico City and New York, all in the United North American States, are labeled some of the worst slums in Citadel space. Mass Effect's future does not look kind for North America.
Also, though the Alliance technically has no oversight on Earth, the Alliance Supreme Court ruled on a Presidential succession crisis in UNAS in the daily news updates after ME2 came out. The Alliance's technical lack of oversight was made a big issue by the side that lost.
I don't remember that. I remember them saying Texas was, though.
